Title: Frame-feed reproducing method of magnetic recording and reproducing device
Inventor: SATOU MASANOBU
IPC: H04N5/783
Filed: 1983-12-09
Abstract: PURPOSE:To stop a head precisely at a required track and to improve the picture quality of still reproduction by travelling a tape until the waveform of a pilot error signal coincides with that of a pilot signal obtained prior to switching at the time of frame feed reproduction. CONSTITUTION:A comparator 1 compares a pilot error signal PE with a previously set up reference value and applies a signal corresponding to the compared result to a gate circuit 4. On the other hand, a monostable multivibrator circuit 2 is triggered at the rise of a switching pulse SP for switching a head and outputs a previously fixed positive pulse PM to a monostable multivibrator circuit 3 and the circuit 3 outputs a positive pulse PMM with pulse width to be immediately before the falling timing of a switching pulse SD. If the pulse PMM is inputted to the gate circuit 4 when a compared signal SC is in the high level, the driving pulse SD is generated, so that a tape travelling capstan roller is driven by a prescribed time.

Title: Artificial biomaterial and method for manufacturing the same
Inventor: MORITA SEIICHI
IPC: A61L27/00
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To provide an artificial biomaterial capable of being bound with bone tissue at an early stage and in a stable state. SOLUTION: A coated layer comprising silica gel and/or silica is formed on a base material, and R-O-Si compounds (R is alkali metal element or alkaline earth metal element) are formed on the surface of the coated layer, Such biomaterial can be manufactured by applying silica gel to the base material, soaking the same in a solution containing alkali metal ion and/or alkaline earth metal ion, thereafter, drying and burning the same. After the artificial biomaterial is laid on a living body, the R-O-Si compounds formed on the surface of the coated layer react with body fluid, the alkali metal ion or alkaline earth metal ion is eluted, and hydronium ion (H3 O<+> ) is taken in from the body fluid. As a result, pH in the body fluid near the material rises, the degree of supersaturating with respect to apatite rises and an environment where the apatite is easily deposited is given.

Title: Bicmos circuit
Inventor: IMAI KIYOTAKA
IPC: H01L29/73
Filed: 1990-08-31
Abstract: PURPOSE:To prevent the generation of through-currents at the time of an input change even at a cryogenic temperature by connecting a diode between the well and source of a P channel MOS transistor driving a bipolar transistor in the forward direction. CONSTITUTION:Since a diode 41 is connected between the well and source of a P channel MOS transistor driving a bipolar transistor 11 in the forward direction, the threshold voltage of the transistor 21 can be increased by a back gate effect. Consequently, when low-temperature operation is conducted, ON voltage between the base and emitter of the transistor 11 and the threshold voltage of the transistor 21 can be equalized approximately. Accordingly, the transistor 11 is brought quickly to an OFF state when an input is changed, thus preventing the generation of through-currents. The collector voltage of the transistor 11 is increased, the saturation the collector voltage is obviated, and operation at high speed can be realized.

Filed: 1983-12-07
Abstract: PURPOSE:To decrease power consumption and to enable long period use of a tape recorder by supplying a 1-pulse current to shift a heat to play position and then supplying the continuous currents to set the head at amusic selecting position, respectively. CONSTITUTION:A logical circuit is actuated with push of a music selection button, and a current flows to a solenoid 5 to suck a plunger 35. Then a trigger arm 4 it turned toward H and a cam gear 3 turns toward F. Thus a projection part 4d of the arm 4 is fitted to a bent part 24b of the gear 3, and the movement of the gear 3 is stopped. When the end of a tape is detected by a tape end detection switch, the logical circuit works to flow a 1-pulse current to the solenoid 5 for stoppage. Then the 1-pulse current flows to a solenoid 10 to attract a plunger 54. Thus the power consumption is greatly reduced since a play mode is kept just by flowing a 1-pulse current to the solenoid.

Since temperature of the steel strip 1 or the α' amount by control of the rolling speed is controlled every pass, plate thickness and the α' amount can be highly reliably and accurately controlled every pass.  Control of the rolling speed which has fear connected to influence for the plate thickness and lowering of productivity is lessened as s mail as possible, and lowering of plate thickness precision and productivity are controlled to a minimum.

Title: Low temperature operating semiconductor device
Inventor: MIYAMOTO MASABUMI
IPC: H01L27/082
Filed: 1989-09-11
Abstract: PURPOSE:To enable rapid operation to be performed at low temperature by a method wherein the impurity concentration in the emitter region is increased to a level exceeding specific value while the impurity concentration in the base region is increased to a level exceeding that in the emitter region. CONSTITUTION:When the impurity concentration in an emitter region is increased, a band gap narrowing problem is posed in the emitter region. Since the band gap is made narrower in the emitter regions than that in a base region 5, this effect is added at low temperature so that the current amplification factor may be decreased to disable the operation. Accordingly, in the base region 5, the impurity concentration is increased to the level exceeding 10<18>/cm<2> to expedite the phenomenon, on the contrary, in the emitter region 2, the impurity concentration is decreased to the level not exceeding that in the base region 5 to restrain the phenomenon. Consequently, injection efficiency of minority carriers from the emitter region 2 is improved by the effect of the energy gap caused through the band gap narrowing in the base region 5, at low temperature. Further, since impurity concentration is high in the base region, carrier freeze-out does not take place nor the base resistance increase.
